I've never played with the kpro open. I just recently demoed the Pure Storm Team and the 003 and I found them to be totally different racquets (I would say the Pure Storm is similair to the 002 non tour). The 003 is stiffer and a 1/4" longer and has more power than the Pure Storm. The Pure Storm has more flex and is a little more control oriented. I went with the 003 because I enjoyed the extra pop it offered.

No headaches!!! It was an easy choice. rds003 is a very solid stick and my serve was a lot harder with more weight then the kpro open. Powerlevel was ideal and i didn't notice the extra length. I can't say anything bad about this racket.
